Diagonal 5.68mm (Type 1/3.2) Frame Readout CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX434DQN is a diagonal 5.68mm (Type
1/3.2) interline CCD solid-state image sensor with a
square pixel array and 2.02M effective pixels. Frame
readout allows all pixels' signals to be output
independently within approximately 1/7.5 second.
Also, the adoption of high frame rate readout mode
supports 30 frames per second which is four times
the speed in frame readout mode. This chip features
an electronic shutter with variable charge-storage
time. Adoption of a design specially suited for frame
readout ensures a saturation signal level equivalent
to when using field readout. High resolution and high
color reproductivity are achieved through the use of
R, G, B primary color mosaic filters. Further, high
sensitivity and low dark current are achieved through
the adoption of Super HAD CCD technology.
This chip is suitable for applications such as electronic
still cameras, PC input cameras, etc.

4. Video signal shading
Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity
so that the average value of the Gr signal output is 150mV. Then measure the maximum (Grmax [mV]) and
minimum (Grmin [mV]) values of the Gr signal output and substitute the values into the following formula.
SHg = (Grmax – Grmin)/150 × 100 [%]
5. Dark signal
Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60°C and
the device in the light-obstructed state, using the horizontal idle transfer level as a reference.
6. Dark signal shading
After measuring 5, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark
signal output and substitute the values into the following formula.
∆Vdt = Vdmax – Vdmin [mV]
7. Line crawl
Set to standard imaging condition II. Adjusting the luminous intensity so that the average value of the Gr
signal output is 150mV, and then insert R, G and B filters and measure the difference between G signal
lines (∆Glr, ∆Glg, ∆Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab).
Substitute the values into the following formula.
Lci = ∆Gli/Gai × 100 [%] (i = r, g, b)
8. Lag
Adjust the Gr signal output value generated by strobe light to 150mV. After setting the strobe light so that it
strobes with the following timing, measure the residual signal (Vlag). Substitute the value into the following
formula.
Lag = (Vlag/150) × 100 [%]
